BUCKET FOR CHAIN PUMPS.

Specification of Letters Patent N o. 12,296, dated January 23, 18155.

To all whom t may concern Be it known that I, EDMUND MORRIS, of the city of Burlington, count-y of Burlington, State of New Jersey, have invented a new and Improved Bucket for Chain Pumps, the construction of which is such that it changes the common lifting chain pump into a suction-pump, without any additional expense.

This improved bucket is made as, follows, reference being had to the accompanying drawings.

A ring of india rubber A, is strained over and on to the conical neck B of the bucket as shown in Figure 2. At each end of this cone are anches O C, which prevent the ring from being forced orf the cone. E E

are spurs cast on the ends of the bucket, /to which the chain is riveted. The gum ring is made so small that when placed on the cone, it will remain, by its own contractile power, at the topor smaller end of the cone. But when the bucket is in use in a pump tube, the friction against the sides of the tube will force the ring down to or toward the base of the cone just enough to make an absolutely water-tight lit, as the ring will in this way expand just suHicient (and no more) to produce and maintain this `fit. The lower lanch prevents the ring from forth.
